多发性骨肿瘤不论原发还是转移严重威胁病人生命,最大痛苦是疼痛难忍晚期止痛就成为主要对症治疗。由于病人肿瘤病灶为多发性单一手术治疗困难。全身外照射虽然达到减症目的但剂量大、视野大、副作用大。药物止痛时间短、反复给药易成瘾。同骨肿瘤内照射止痛剂能有效镇痛,减少麻醉药品剂量,增加病人抗肿瘤信心维持正常生活。我们用~(90)Y—EDTMP骨肿瘤内照射止痛剂治疗了35例晚期多发性骨肿瘤病人,镇痛效果满意。观察总结如下: Multiple bone tumors, whether primary or metastatic, are a serious threat to the patient’s life. The greatest pain is pain and pain. Advanced pain relief has become the main symptomatic treatment. Because the patient’s tumor lesions are difficult to treat with multiple single operations. Although the external body irradiation achieves the purpose of reducing the disease, the dose is large, the visual field is large, and the side effects are large. The short duration of drug analgesia and repeated doses make it addictive. Internal bone tumor analgesics can effectively relieve pain, reduce the dose of anesthetic drugs, and increase the patient’s anti-tumor confidence to maintain normal life. We used ~(90)Y-EDTMP intra-tumor radiation analgesics to treat 35 patients with advanced multiple bone tumors with satisfactory analgesia. The observations are summarized as follows:
